Bear in mind that, in addition to concerns about maintaining compatibility, there are other companies who influence what features of the phone can be used directly by third-party developers. Apple has spent many years and millions of dollars establishing these relationships and isn't going to jeopardize them to make it easier for someone to write a game for the phone, especially when it can be done with clever coding instead. Smart hackers tend to enjoy working around such limitations.
